SpamAssassin not checking

I have a server and SpamAssassin is not checking any of the messages for spam. The exim_mainlog just has entries of:

Warning: "SpamAssassin as user detected message as NOT spam ()"

what is a setting that I need to check to insure that exim is properly passing the messages on to SpamAssassin?

 

Yea. When I run just spamd from the command line, I'm getting a lot of Out of memory messages:

Code:

[2639] info: spamd: server started on port 783/tcp (running version 3.2.4)

I bet this is the problem, but I don't know what the problem is. I don't think the server is out of memory.

Code:

root@server [~]# free -m
             total       used       free     shared    buffers     cached
Mem:          3948       3045        903          0        200       2409
-/+ buffers/cache:        434       3514
Swap:         1992          0       1992

 

Seems to affect every user, not any one particular user.

I did try sending the GTUBE string to an e-mail address on the server, it showed the same symptoms. I then renamed the .spamassassin directory for that user to .spamassassin.out and tried the GTUBE string again, and got the same results.
